Wally West and Cisco have returned to Central City, however the good news doesn't last long. The speed force is dying due to the power enhancement Barry got from Spectre during Crisis. Wally confronts Barry about not telling him there was anything wrong with the speed force which leaves Wally angry. Meanwhile, Frida Novikov aka Turtle 2.0, a metahuman who can manipulate time, shows up to murder an informant, but is later defeated by Wally and Barry. Later, Cisco is attacked by Thawne, who has taken over Nash’s body and as a result, has no speed powers. After he gets incapacitated by Cecile, Thawne is then imprisoned in the pipe line. This gives Barry the idea to create his own speed force, now that the original speed force has died, so that he doesn’t lose his speed when the residual speed force energy in his body wears off. Elsewhere, Kamilla discovers a digital photograph that reveals mirror Iris' true nature, but is then shot by the Mirror gun by Mirror Iris.
